CT-S3100 is a two-component addition-type silicone thermally conductive potting compound. This product consists of two components, A and B. Component A is gray-black and component B is white. When the two components are mixed evenly at a weight ratio or body ratio of 1:1, they will solidify into a gray flexible elastomer.
This product has low density, low viscosity, and good fluidity. It can be manually potted or automatically potted by a dispenser. It has a fast curing speed and can be cured at room temperature or heated. The cured product is resistant to ultraviolet rays, has good anti-aging performance, and has good repairability. It has the characteristics of flame retardancy of UL94 V-0 and high thermal conductivity. It has good disassembly. The sealed components can be taken out for repair and replacement, and then repaired with this product. It is particularly suitable for potting and sealing of electronics, electrical, circuit boards and inverters.
